SUMMARY
The discussion focuses on calculating the distance traveled by a 9.0 kg object subjected to a net force of 6.6 N east, resulting in a uniform acceleration. The correct acceleration is determined to be 0.733 m/s² using Newton's second law (F=ma). The distance traveled during acceleration is calculated using the kinematic equation vf² = vi² + 2ad, leading to a distance of approximately 2 meters. The confusion arises from an incorrect answer key stating 6.1 m west, which contradicts the established direction of motion, as both force and velocity are directed east.
